You're right that Mt. Igneus is currently the best place for training Sp. Atk, but it is definitely not efficient, only suitable for beginners or Pokemon at low levels. The Hiker only gives 3 Sp. Atk per fight in total, and Heatmor is rare inside, so it is a slow process comparing to training Physical Attack, Defense and Speed. HP training is also not efficient in this way.

Well, if you reckon that we have enough content on the subject of Effort Values, go ahead.
